Photovoltaic module with good MC4 plug sealing effect

Abstract

The invention is applicable to the technical field of solar photovoltaic application, and provides a photovoltaic module with a good MC4 plug sealing effect, which comprises a photovoltaic module plate, a comprehensive pipe gallery, a sealing cover, a positive MC4 plug, a negative MC4 plug, blocking sleeves and a photovoltaic cable, wherein the photovoltaic module plate is located on one side of the comprehensive pipe gallery, a plurality of blocking sleeves are arranged in the comprehensive pipe gallery at intervals in the length direction of the comprehensive pipe gallery, and as the comprehensive pipe gallery provided with themultiple blocking sleeves is arranged and the multiple blocking sleeves are distributed in the comprehensive pipe gallery at intervals, part of the blocking sleeves are provided with inner holes for the positive MC4 plug and the negative MC4 plug to penetrate through, and therefore space in the comprehensive pipe gallery can be sealed in a segmented mode, and meanwhile installation of the MC4 plugs is not affected. Besides, the maintenance hole used for maintaining the plug is further formed, and the sealing cover with the sealing ring is installed in the maintenance hole, so that the comprehensive pipe gallery and the MC4 plug are fully sealed.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic applications, and in particular relates to a photovoltaic module with good sealing effect of MC4 plugs. Background technique [0002] Solar power generation surface technology is a clean energy technology that countries all over the world are competing to develop. Solar power generation surface technology makes full use of clean solar energy resources, and the vast linear space of roads will be able to realize Metal materials such as photoelectrically converted monocrystalline silicon wafers, polycrystalline silicon wafers, and thin film silicon wafers are paved on the road surface, turning the existing asphalt concrete pavement or cement concrete pavement into a huge solar energy collection platform, and the clean electric energy converted from solar energy is passed through Electrical components and equipment are integrated into the national grid or collected into the energy storage s...

AI Technical Summary

Problems solved by technology

[0003] Based on the implementation of the comprehensive application test section project of solar power generation surface technology in the expressway and the follow-up observation in the later period, it was found that the positive and negative MC4 plugs leading out of the photovoltaic module board were directly buried in the road material filled in the power trench, It is not conducive to later maintenance and maintenance, and it is easy to cause damage to the positive and negative MC4 plugs during power trench filling and maintenance construction

In addition, when it rains, there will be water in the groove, and the rainwater will seep from the connection of the positive and negative MC4 plugs, which will easily cause the MC4 plug to heat up or short circuit, seriously affecting the stability and durability of the positive and negative MC4 plugs.
